Abstract
This study aims to investigate how accurate are TASMICS and TASMIP models in predicting the X-ray output of some Conventional Radiology X-ray units with high frequency generators. The X-ray output in microgray per milliampere seconds (μGy/mAs) at 100 cm from the X-ray tube was determined for selected high voltages and taking into account the total filtration. The X-ray output was then measured directly with the multi-purpose detectors (MPD), Raysafe X2. The maximum relative error between measured and predicted values was found to be equal to 20%. The maximum relative error between measured and predicted values obtained demonstrates the difficulty of accurately predicting the X-ray tube output using TASMICS and TASMIP models since they are based on fixed anode angles and different composition of the tungsten anode.

Summary
Several computational methods are used to characterize X-ray spectra. Boone and Seibert [1] reported on a method for computing X-ray spectra based on the method of interpolating polynomials, called TASMIP, this model computes tungsten anode X-ray spectra in 1 keV energy bins between 30 and 140 kV and provides accurate spectral estimation based on the measurements of Fewell et al [2]. J.H. Hernandez and J.M. Boone [3] later developed a new method named Tungsten Anode Spectral Model using Interpolating Cubic Splines (TASMICS).
